Java解压缩zip包+rar包兼容rar4和rar5兼容多操作系统

业务背景：需要将zip包或者rar包进行解压缩，需要兼容rar4和rar5两种版本

maven 依赖包：

亲测，rar4和rar5两种版本的都可以解压

但是后来发现解压缩zip包的时候，如果是mac系统会出现乱码情况，因为mac系统zipFile默认是utf8编码格式，但是window认gbk编码格式，所以mac文件到使用gbk就会出现乱码格式，因此需要使用同时兼容多种操作协同的读取方式

使用

<dependency><groupId>org.apache.ant</groupId><artifactId>ant</artifactId><version>1.10.10</version>
</dependency>

ZipFile文件格式进行处理即可解决

public static void unzip(String srcPath, String destDirPath) {File srcFile=new File(srcPath);if (!srcFile.exists()) {throw new RuntimeException(srcFile.getPath() + "所指文件不存在");}// 开始解压ZipFile zipFile = null;try {zipFile = new ZipFile(srcFile);
//            zipFile = new ZipFile(srcFile, Charset.forName("GBK"));  //含有中文 使用java.util.zip才需要指定这个，后面即使指定了也还是有问题，所以放弃这个改成Ant.jarEnumeration<?> entries = zipFile.getEntries();while (entries.hasMoreElements()) {ZipEntry entry = (ZipEntry) entries.nextElement();System.out.println("解压" + entry.getName());// 如果是文件夹，就创建个文件夹if (entry.isDirectory()) {String dirPath = destDirPath + "/" + entry.getName();File dir = new File(dirPath);dir.mkdirs();} else {// 如果是文件，就先创建一个文件，然后用io流把内容copy过去File targetFile = new File(destDirPath + "/" + entry.getName());// 保证这个文件的父文件夹必须要存在if (!targetFile.getParentFile().exists()) {targetFile.getParentFile().mkdirs();}targetFile.createNewFile();// 将压缩文件内容写入到这个文件中InputStream is = zipFile.getInputStream(entry);FileOutputStream fos = new FileOutputStream(targetFile);int len;byte[] buf = new byte[2048];while ((len = is.read(buf)) != -1) {fos.write(buf, 0, len);}// 关流顺序，先打开的后关闭fos.close();is.close();}}} catch (Exception e) {log.error("解析压缩包文件异常:{}",srcPath);throw new RuntimeException("unzip error from ZipUtils", e);} finally {if (zipFile != null) {try {zipFile.close();} catch (IOException e) {e.printStackTrace();}}}}
